For smaller builds like the cockroaches or the tarantula - ball joints all the way I'm afraid - 4 ball joints can more than hold up any reasonable weight - but the Goliath doesn't have any ball joints, it makes use of the click joints featured in the Exo force sets - some of the best tools too mecha building known to man.

I don't get this whole "Ball joints are loose" shit - so long as you don't fuck around with them they are no different in movement range or tensile strength to the same joint made in technic.

Anorak Natalya, won't let me sit around all day playing with my balls.

One of the many vehicles the Immortal Empire have brought with them from their previous inter-galactic conquests - the "Badger" has reasonable speed and load capacity with 1 driver, 1 gunner and room for three passengers - it appears to be loaded with a dual-mounted GT-rocket launcher. These have been employed en-masse against Scythian targets as a softening tactic before hitting us with more powerful weapons.

Immortal Artillery

Designation - "Hydra"

A slow moving and ugly beast - the Hydra is an 8 wheeled Artillery piece armed with twin H.I.V.E cannons and a real time data uplink to the Immortals data links for target spotting, it is also extremely heavily armored and has been used as a battering ram against Scythian fortifications once its main gun is either out of ammunition or no longer of use.

Immortal VTOL

Designation - "Skyhawk"

Gentlemen, we are going to be blunt - we have no idea how the hell this thing works. The "Skyhawk" is a single man VTOL armed with twin rotary H.I.V.E autocannons - capable of high speed maneuvers and to be quite frank, it shits on every land-based vehicle we have at our disposal.

Our R&D teams have managed to come to a few distinct conclusions - this craft must be powered by some form of onboard reactor combined with a gravity drive - as its speed, weight and profile all lead to the fact this thing should not fly at all. Secondly - the "Skyhawk" seems to be giving off all the readings of an open dimensional portal or wormhole - which was an utter mystery until we managed to salvage one of its autocannons from the wreckage of an undisclosed battlefield.

The "Skyhawk" does not carry its own ammunition - but rather the weapon is linked to an open wormhole to an ammunition feeder system in an unknown location that simply feeds the ammunition into the wormhole and directly into the barrel of the gun. The only reason this craft would ever need to land is due to pilot fatigue - which the Immortals answered with this -

Immortal Drone VTOL

Designation - "Murderhobo"

The "Murderhobo" class VTOL drone is a undefended worlds worst nightmare, an advanced AI connected to a gravity drive and a black hole generator - it can run for all eternity, it never needs to stop, it never needs to sleep, it never needs to stop killing.

Which it excels at by the way.

It is armed with a central nose mounted OT-Positron cannon, capable of turning most heavy vehicles and structures into molten slag in a heartbeat - and if that was not enough, the next two guns from the center are RT-Lance Lasers, designed not to destroy vehicles - but melt their crews from the inside out with radiation and raw RT power.

The last two guns on each wing-tip are GT-Lasers - anti-infantry cannons capable of rapid fire and setting their targets alight from even long range - they ravage with impunity as the "Murderhobo" takes passes at close range, laying waste to most targets in a single pass.

Immortal Jaguar Armored Car Variant

Designation "Quarterback"

After arriving in the brikverse the Immortals ran into something they had not seen before - a small and effective Armored Car known as the Jaguar - usually a one or two man vehicle with enough weapons to take on most light tanks and infantry. So doing what they do best, they found the place that built them, conquered the fuck out of it and then set about building their own version.

Armed with heavy Armour, a mounted twin-flachette autocannon and no less than 6(!) missile launchers, the "Quarterback" is set loose in waves in urban environments to blitz enemy fortifications for heavier units to then turn into mulch - it has quickly become a favored tactic amongst the Immortal armored divisions to boot.

Unknown - Presumed Immortal Jaguar Armored Car Variant

Designation - "Ugly Betty"

Salvaged from the 2nd battle of Mousetrap - this vehicle seems to be of Immortal construction - but of a much lower Tek level - and is a 6 wheel chassis with a massive flak cannon mounted on its rear half.

The only conclusion is that someone who had only seen a Jaguar in passing attempted to build a version of it for themselves with what they had at hand and let it loose with the Immortals just to see what it could do. The effectiveness of this tactic remains to be seen.
